Wiegand, 2001b: An uncommon plant species occurring in rich floodplain forest on slightly elevated terraces above the river between the C&O Canal and the more open, scoured bedrock. Several dozen flowering Wild blue phlox (Phlox divaricata) were growing in a rich sandy substrate beneath a partial canopy Wild blue phlox is fairly common and widespread immediately upriver, so it probably occurs at other locations within this survey site. Found at 2 sites.
